This invention is for =-street lighting standards and ha for its biieet a w tendand wh ch som bines both a means ;for ,iig-hting the surface pi a thoroughfare and means which permit the standard itself {to constitute a line-of direction for li i f p moving along the said surface.

Such signal lights will preferablybe arranged to reflect the light in any desired direction.

Further, the light from the illuminating unit may be such as to give a decorative effect to the standard, for example it may be coloured or the colour of the light may be periodically varied so as to give a kaleidescopic effect, but it is to be understood that the essence of the invention resides in the employment of a means of illumination upon a standard, wherein the major portion of the light is employed in illuminating the surface of the standard, so as to give it a floodlighted effect.

One form of construction of illuminating unit for use in connection with the present invention is illustrated in Figures 2 and 3 and comprises two semi-circular elements similar to the element illustrated in Figure 3 hinged together at 5 in the form of a bracelet, each provided in the interior thereof with a lamp 6, for example a fluorescent tube, mounted in each segmental section so as to ow light upWardly and downwardly through upper and lower windows 1 and 8 provided with transparent or translucent lenses 9 and I constructed so as to cast the beam of light emitted from the lamps 6 over the major portion of the surface of the standard, which the unit encircles. Each semi-circular portion of such an illuminating unit can be formed primarily out of two semicircular metal stampings II and I2 (Figure 3) arranged concentric with one another and joined to one another by V-shaped brackets l3 mounted between the stampings so that the base of the V constitutes the holder for the semi-circular fluorescent tube 6 arranged in the annular space provided between the stampings. The annular openings at the top and the bottom of the unit which form the upper and lower windows land 8 support the glass lenses 9 and Ill constructed and arranged so that when the unit is in position upon a standard and the lamps are lighted the lenses throw the light over the surface of the standard. The semi-circular units are hinged to one another so that the jaws of the unit can be opened out and placed around the standard in the form of a bracelet and then closed so that the two halves of the unit completely encircle the surface of the standard. The electrical connections for the lamps 6 carried by the unit extend inwardly and through apertures in the metal sides l2 and thence into the standard, and can be connected to the electrical cables extending through the standard by means of plugs which can be easily removed from their sockets and thereby permit the illuminating unit to :be removed from the standard as a complete article and so provide a simple and efficient means of mounting such -illuminating units both on standards already erected and standards constructed for the provision of such units.

With the unit above described, the light, as hereinbefore stated, can be thrown upwardly and downwardly over the entire surface of the standard. If necessary, however, the downwardly directed light can be directed into a shield [4 (Figure's 4, and 6) which extends from the underside of the illuminating unit 2 to apoint adjacent to the ground. The shield can be arranged totaper 4 downwardly and form an annular space 15 between the standard and the shield. The shield 14 can be provided with apertures along the length thereof in which there are mounted prismatic lenses 16 (Figure 7) which when the light is thrown downwardly from the illuminating unit, reiract the light through piano-convex lenses l1 into a horizontal beam which will be emitted from the lower end of the standard and constitute a signal light or lights for traffic.

and "the standard at the lower end of the shield,

for drainage purposes.

In order to support the unit hereinbefore described upon a standard, there is preferably provided-around the surface of the lamp at the desired height above ground level, for example eight to nine feet, a stop ring 20 (Figures 1, 2 and 6) upon which the unit rests.

It will be appreciated that where the light from the illuminating unit is cast upwardly and downwardly over the surface of the standard, the lower half of the standard offers considerable assistance under foggy conditions to traffic travelling along a road.

It is to be understood that the illuminating unit or units may comprise a violet or substantially violet light visible in character, which casts a beam or beams over a reflecting surface of the standard for example a white surface, so as to give the said surface of the standard a fluorescent effect.

Thus it will be seen that according to the present invention there is provided a lighting standard, which is not only effective in appearance, but also provides a very efficient means for indicating to traffic the line of direction of the road upon which they are travelling.

- What I claim as my invention and desire to secure by Letters Patent of the United States is:

1. An illuminating device for the exterior surface of a pole, comprising a unit adapted to surround an intermediate portion of a pole, said unit comprising a substantially annular inner sleeve of internal diameter to fit over the outer surface of the pole to which the unit is applied; a substantially annular outer sleeve concentrically dis- .posed with respect to said inner sleeve and spaced outwardly therefrom; radially extending brackets having their ends secured to the said sleeves and maintaining them in concentric, spaced relation, each of said brackets having a notch along its upper edge; and a substantially annular illuminating tube positioned between the sleeves and supported within the said notches in the radially-extending brackets for casting beams of light upwardly and downwardly along the exterior surface of a pole on which said unit is mounted.

2. An illuminating device as defined in claim 1, in which the unit, including the sleeve and illuminating tube, is substantially annular and is composed of two substantially semi-annular portions, hinged to one another at one end of each of the said portions whereby the unit may be readily placed about a pole to encircle the same, and in which means are provided at the other ends of the said portions for securing said ends together, whereby to secure said unit about a pole.

3. An illuminating device for the exterior surface of a pole, comprising a unit adapted to sur round an intermediate portion of a pole, said unit comprising an inner sleeve, an outer sleeve concentrically disposed with respect to said inner sleeve and spaced outwardly therefrom, the upper and lower edges of said sleeves being disposed, respectively, in the same planes and being turned inwardly toward each other with a space therebetween, brackets connecting said sleeves and maintaining them in concentric, spaced relation, i1- luminating means positioned between the sleeves and supported on said brackets for casting beams of light upwardly and downwardly a1ong the exterior surface of a pole on which said unit is mounted, and lenses mounted between the sleeves at the upper and lower edges thereof and retained in position by the inturned edges of said sleeves.
